I keep my eye on $VIX (live chart) even though it's movement most times lags price. My main ones I watch are $TICK, $TIKND and TIKRL. I might have to quit trading if they ever stopped providing them.
Maybe VIX going to do a back-test of the break of the trendline. Your observations were definitely relevant for some ST traders.
It was on my radar but just didn't have enough bandwidth to catch it. Great day for Silver, bitcoin and natural gas.
Volatility slowed likely to continue this way, for the most part, into the close ... with CPI report @ 830am tomorrow morning.
